Service Manual for OF5300/5600
Chapter 0 Introduction

Functionality The OKIFAX 5050 is technically similar to the OKIFAX 5300. The physical appearance is identical to the OKIFAX 5300; however, the OKIFAX 5050 is strictly a stand-alone facsimile product. Although there is a PC Interface connection socket on the OKIFAX 5050's Main Control Board, this socket is not functional, and the PC Interface cannot be used on this product. This socket will only be used to update Flash ROM using the High Speed Loading System. In addition, the OKIFAX 5050 will only accept the 1.5 MB Memory Option (with battery back-up), and the 1 MB Memory Option (without battery back-up). Other than the lack of PC Interface and optional memory capability, there are no other functional or operational differences between the OKIFAX 5050 and the OKIFAX 5300. Hardware There are two hardware (spare part) differences between the OKIFAX 5050 and OKIFAX 5300. The following parts are unique to the OKIFAX 5050: P/N 55083101 1. Main Control PCB (E17-3 PCB) 2. Operator Panel Assembly (Contains the OKIFAX 5050 logo) P/N 55083210 Firmware For First Production Release Firmware Information, refer to Product Bulletin # E708 (on the back of this sheet). Standard Memory The OKIFAX 5050 has 256kb of standard document storage memory. Documentation OF5050 User Guide OF5050 Quick Start Guide Options 1.5 MB Expansion Memory with Battery Back-up 1.0 MB Expansion Memory without Battery Back-up 500 Sheet Letter/Legal Paper Tray Telephone Handset Consumables Drum and toner Toner Cartridge Image Drum Kit

P/N 70031501 P/N 70029101 P/N 70029401 P/N 70031801

same as the OKIFAX 5300/5600 P/N 52106701 P/N 56116901

Service Procedures When servicing the OKIFAX 5050, refer to the maintenance procedures for the OKIFAX 5300 in the OKIFAX 5300/5600 Service Manual. The OKIFAX 5300 procedures apply to the OKIFAX 5050. Service Authorization All OKIFAX 5300/5600 Authorized Service Providers will automatically be authorized to perform warranty repairs on the OKIFAX 5050.

This Flash firmware version is incorporated in first production release of the OKIFAX 5050. Changes: None (First Production Release) Note: The OKIFAX 5050 uses Flash ROM to store firmware and configuration changes. These ROMS are not socketed, and cannot be physically replaced. The Flash ROM version is field upgradable using two methods: 1. Replace the OKIFAX 5050 Main Control PCB (E17-3 PCB, part number 55083101). Replacement boards should always contain the current version firmware. 2. Use the Remote Management Center System (RMCS) to upgrade Flash ROM remotely via the telephone. The "RMCS" is a remote diagnostic system, that may be purchased by authorized OKIDATA dealers that allows remote programming and diagnosis of OKIFAX machines via telephone. The OKIFAX 5050's Flash Firmware can also be updated remotely using this tool. For more information regarding the availability and/or purchase of an OKIFAX RMCS system, please contact your OKIDATA Sales Representative.

Image Drum (ID) Unit (already installed) Toner cartridge Recording paper Document stacker

(02) Procedure 1) Toner cartridge



Peel off the fixed tape attached to the copy stacker. Open the document table and copy stacker. Take the cushion out of the ID unit.

Toner Cartridge Installation (Figure 2.5.2.1)

Toner Cartridge Installation 2 (Figure 2.5.2.2)

Toner Cartridge Installation 3 (Figure 2.5.2.3)



Take out the toner cartridge from the damp proof bag, shake it five or six times as shown in the illustration to eliminate the toner deflection, and peel off the seal gently.



Ensure that the plastic tab on the right-hand side of the toner cartridge recess lines up with the groove on the toner cartridge. Press down on both ends to make sure the cartridge is fully seated.

Toner Cartridge Installation 4 (Figure 2.5.2.4)



Push the blue tab forward until it stops.

Toner Cartridge Installation 5 (Figure 2.5.2.5)



Clean the toner scattered in the vicinity of the toner cartridge using a cloth moistened with cold water. Do not use hot water since it makes the toner stick there. Close the copy stacker until the buttons have been locked completely.

Recording Paper Cassette Installation 1 (Figure 2.5.2.6) (3) Recording paper Note: About 250 sheets of the new paper can be set in the recording paper cassette.



Remove the paper cassette from the facsimile by pulling the cassette tab.



Sheets must not exceed the paper full marker of the new paper limit indication. If excessive sheets are set, it will cause paper jams. After loading the new paper, push it forward into the slot at the front of the facsimile until it locks.

Chapter 2 Installation Procedures

This function is used for the purpose of TEL/FAX automatic switching as discussed below. It assumes that an optional handset is connected to the machine. (1) If the machine detects a call with a CNG signal indicating an auto send facsimile call, it starts an automatic document receiving operation. (2) If machine detects a call without a CNG signal, machine generates the buzzer sounds as a telephone call. The calling person can hear a "ring back" tone within a predetermined time. If the operator at the called side does not lift the handset within the predetermined time, the machine automatically starts a document receiving operation. Voice conversation will automatically be available through the internal handset by lifting up the handset while the call buzzer is sounding. Note: In this mode, following four settings are required. 1: The predetermined time is selectable between 20 or 35 sec. (Function program No. 10) 2: No ringing signal is sent to the external telephone handset. TEL/FAX Mode Flowchart
